Creator data select to Data Prep

Typically I set up my data structures in Creator to 'test' the data and then create the .hyper properly in Data Prep. It would be really great if it was possible for Data Prep to take the Creator data structure to give me a head start. In essence Data Prep to 'see' the Creator data selections. THis would be great as it would allow significant time saved in cleaning data an .hype rebuild.
